Don't know if you had an answer on this, and I'm interested in the "will an 18" fit underneath?" question. Sure there are those out there who would also say no way should you drive with a temporary smaller wheel but surely for a v short distance to get you out of harms way its not a problem?

Other thought - Van coming with factory standard 16" rims on - if I change them for 18"ers will my speedo be out?

cheers

if you increase rim size you decrease tyre wall size to the overall circumference remains the same. On the driver's side A pillar there should be a label telling you acceptable tyre sizes and pressures?

I think you could have problems with ABS and various other electronic traction functions. On the SE then the minimum wheel size would have to be 17" because of the larger brakes on the front and on a 4Motion I think you could have some serious problems.
You could probably fabricate some form of extension to the spare wheel carrier to fit a larger wheel.

27.03 diamèter on those 19 inch wheels it is only 24.05 on the 17 inch thunders, that will surely affect some of the electronics and milometer?

I have heard that a 17" is the largest that will fit, but I may be wrong on that.

There are some websites that allow you to plug in tyre size and it will calculate rolling radius and tell you your speedo error compared to your standard set up. FWIW, I plugged in the VW's standard issue specs for the Cali and they were all extremely close in terms of rolling radius (RR).

215 65 R16
235 55 R17
255 45 R18

The middle one had the largest RR and the first and last were closest, although even the R17 was only a fraction of 1 mph out compared to the others. One would expect them all to be very close, after all!

The bottom line is that you can run any of the above as your spare, if it will fit. The R16/17 combos effectively have the same RR as the 18", so personally I would be happy running the smaller wheel as the spare on a vehicle with 255 45 R18 wheels.
